Member Function Documentation

void PardisoSolver::diagonalChanged ( int  idiag, int  extent  )

virtual

called if the diagonal elements of the matrix have changed. Triggers a refactorization of the matrix, if necessary.

Parameters

idiag	index of the first diagonal element that changed
extent	the number of diagonal element that changed.

Implements DoubleLinearSolver.

void PardisoSolver::firstCall ( )

virtual

int PardisoSolver::getNumberOfNonZeros ( DenseSymMatrix &  m )

private

int PardisoSolver::matrixChanged ( )

virtual

called if some elements of the matrix have changed. Triggers a refactorization of the matrix, if necessary.

Implements DoubleLinearSolver.

void PardisoSolver::SetUpPardisoSolver ( SparseSymMatrix *  sgm )

private

void PardisoSolver::solve ( OoqpVector &  x )

virtual

solves a linear system.

Parameters

x	on entry the right hand side of the system to be solved. On exit, the solution.

Implements DoubleLinearSolver.

void PardisoSolver::solve ( GenMatrix &  rhs )

virtual

Reimplemented from DoubleLinearSolver.

void PardisoSolver::solve ( GenMatrix &  rhs, int *  colSparsity  )

virtual
